--	Below these comments: Internationalization table
--	How to translate this module (for languages without variants):
--	• Characters inside single and double quotation marks are called strings.
--	  The strings in this i18n table are used as output.
--	• Strings within square brackets are keys.
--	• Strings are concatenated (joined) with two dots.
--	• Set the string after «local lang =» to your language's code.
--	  Change the first key after "i18n" (usually "en-GB") to the same thing.
--	• For each string which is not inside a function, translate it directly.
--	• Strings with keys named "format" are Lua regular expressions.
--	  «()» is a match; «.+» means all characters; «%s+» means all spaces.
--	• For each string which is concatenated to the variable «var»,
--	  translate the phrase assuming that «var» will be a noun.
--	• Remove any unnecessary translations.
